Has anyone ever tried using steel in place of stone for oven pizza cooking? I just noticed this kickstarter linked below that claims steel makes for great pizza. I would think that steel would lose its heat faster than stone but I suppose that might be a good thing if that heat is going into the pizza faster. It just seems to me that stone vs steel for pizza baking would be like the difference between cast iron and aluminum for a frying pan. Both can get very hot, but the second options wouldn't be able to build up as much heat as the first.
